Hastelloy W Chemical Composition
Hastelloy W Material Properties Overview
As a manufacturer and supplier in China, Arialloy offers competitively priced hastelloy W products.
Hastelloy W (UNS N10004) is a nickel based superalloy strengthened primarily by solid solution hardening. Its nominal composition contains approximately 63% nickel, 24% molybdenum, 5% chromium, and 6% iron. Molybdenum strengthens the nickel matrix and contributes to resistance in reducing environments, while chromium supports surface passivation. The alloy combines substantial mechanical strength with useful ductility and good weldability. Processing condition is important because deformation and thermal exposure can alter its mechanical response. Intermediate annealing during fabrication helps restore ductility after working. Wrought bar is typically solution treated at 1185°C and rapidly cooled, with the heating cycle and cooling method selected according to product dimensions and the applicable specification. This treatment also assists subsequent fabrication operations.
Compatible welding processes include gas tungsten arc welding, gas metal arc welding, and shielded metal arc welding. Sound weld formation requires clean surfaces, effective shielding, and suitable heat input. For dissimilar joints, dilution and the properties of the materials being joined influence the final strength, ductility, and response to subsequent heating.
Hastelloy W Corrosion Resistance
The high molybdenum content of hastelloy W provides a metallurgical basis for resistance to reducing media. Chromium contributes to surface passivation, while the nickel matrix supports the alloy’s overall corrosion performance.
Actual resistance depends on acid concentration, temperature, dissolved oxygen, and oxidizing impurities. Its relatively low chromium content warrants careful evaluation in strongly oxidizing solutions. Resistance to pitting, crevice corrosion, and stress corrosion cracking should be established through testing under representative conditions, particularly when assessing weld metal whose composition has changed through dilution.
Hastelloy W Mechanical Properties
In room temperature testing, solution treated hastelloy W bar (AMS 5755) exhibits typical tensile strength of 965 MPa, 0.2% offset yield strength of 520 MPa, and elongation of 51%. For GTAW weld metal in the as welded condition, corresponding values are approximately 830 MPa, 550 MPa, and 35%, respectively.
Hastelloy W Temperature Characteristics
Hastelloy W retains substantial strength at elevated temperatures, with typical bar tensile strength of 610 MPa at 760°C and 415 MPa at 871°C. Its melting range is approximately 1290°C to 1375°C. Prolonged heating can alter strength and ductility.
After 1000 hours at 650°C, GTAW weld metal exhibits increased room temperature strength but reduced elongation, from 35% to 14%. These results demonstrate that thermal exposure can change mechanical properties, so temperature capability must be assessed alongside exposure duration, stress, and the surrounding atmosphere.
